I watched a scean like that about 8 years ago in Yellowstone. People just didn't give the herd the room they should have and when the herd bull charged there were cameramen scattering all ways.
I was 150 yards away on a hillside watching with 3 young boys.
The rangers had to order everyone to get back to there cars.
But i agree, the dude with the cammera stuck to his eye has brass **** or something
A friend of mine came across 5 bull moose in the bush a few years back and took about 30 pictures but never looked through the view finder one time. He got one shot with 4 of the 5 bulls in it.
